LOOM-SHUTTLE.

Specification of Letters Patent.

Patented March 6, 1906.

Application filed February 11, 1905. Serial No. 245,184.

.To all whom it may concern:

Be it known that I, ROBERT D. FRASER, a citizen of the United States,residing at Lewiston, in the county of Androscoggin and State of Maine,have invented certain new and useful Improvements in Loom-Shuttles, ofwhich the following is a specification.

My invention relates more especially to shuttles which are filled andthreaded automatically, but is applicable to others.

In such automatic shuttles as heretofore made it is found impossible toprovide for the even pull on the yarn which is necessary in making afirmsmooth selvage, since the dra of any frictional surface which can beplace in the space available in the interior of the shuttle will greatlyvary with the amount of yarn on the bobbin and becomes practicallynothing when several loops of yarn slip off the bobbin at once.

The object of my invention is to provide for an even pull on the fillingyarn at all times and it consists, rimarily, in a construction whichinsures a i fictional drag on the fillingyarn in the immediateneighborhood of the delivery eye or slot through which it passes outthrough the side of the shuttle.

In the accompanying drawings, Figure 1 is a plan of the shuttle inpartial section, and Fig. 2 is a full size elevation of the part of theshuttle with which my invention is concerned.

In the drawings, B is the bobbin, S, a guiding-slot which may have africtional bushing; E, the outlet-eye through which the yarn leaves theshuttle; F, a frictional surface which I prefer to make by inlaying andcementing in a piece of felt which extends for a short distance oneither side of the outlet-eye E. I do not limit myself to the preciseshape shown, since good results may be obtained when it is made sonarrow that it may be considered merely a bushing for the outlet-eye Ebut I prefer the shape shown in the drawings, as it gives more frictionand wearing surface and does not extend backward far enou h to strikethe shuttle-binder nor sidewise ar enough to rub against the warp.

My invention is not concerned with the internal construction of theshuttle; but I prefer to give the yarn a free channel, as shown, sincethe doubling of it around the corners will give it drag enough to bed itin the soft felt F and insure the shuttles pulling up a firm selvage.

My improvements call for no change in the manner of using the shuttle.

Having now fully described my invention and the manner of using it, whatI claim, and desire to secure by Letters Patent, is

1. In a loom-shuttle having a delivery-eye, the combination with theshuttle-body of a frictional piece inlaid in its outer surface adjacentto the delivery-eye, substantially as set forth.

2. In a loom-shuttle having a delivery-eye, the combination with theshuttle-body of an inlaid frictional piece which forms the outer edge ofthe delivery-eye, as and for the purpose set forth.

3. In a loom-shuttle, the combination with means of producing a drag onthe' yarn while it is in the shuttle, of a friction-surface on theoutside of the shuttle over which the yarn passes after leaving thedelivery-eye; substantially as and for the purpose set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
